What Job Is the Audience Hiring the Encore To Do? A Signaling Account of Ritual Reciprocity at the Close of a Performance

An encore looks like more concert. We argue it functions more like a receipt. Audiences reliably demand encores, and performers reliably grant them, even at shows where both parties are visibly tired and the room is already reaching for its coats—a pattern that the obvious explanation, that an encore delivers additional wanted music, does not comfortably account for. Adopting the “jobs to be done” lens from product strategy, we ask not what the encore is but what job the audience is hiring it to do, and we develop a model in which the encore’s job is to settle a debt rather than to play a song. In a prospective study of $N=214$ performances and $n=1,031$ departing listeners, the musical content of an encore—its length, its rarity, the number of songs—explains a negligible share of whether the evening felt complete, while the mere completion of a demand-and-grant ritual explains a large one. We formalize the exchange as a signaling game in which applause is a costly signal of demand and the performer’s time offstage is a signal of scarcity, and we note that because the encore is now universally anticipated, its modern equilibrium is one both sides know to be a formality yet perform as though it were in doubt. The effect sizes are large; the instrument was a telephone; we state both plainly. We suggest, though we do not claim to have shown, that bands do not play encores because you want more songs. They play them because everyone needs the night to end on purpose.
